Description

AIR SLIDE CONVEYOR AND USE OF AN AIR SLIDE CONVEYOR
Field of the invention
The invention relates to an air slide conveyor comprising a plenum chamber configured to receive compressed gas from a gas supply system, and a conveying deck forming a top side of the plenum chamber as defined in the preamble of independent claim 1.
In suspension smelting, such as in flash smelting, fine-divided matter such as sulfidic concentrate is usually fed to a concentrate burner or to a matte burner of a suspension smelting furnace by using feed systems comprising an air slide conveyor. It is known in the art to use porous metal plates in the conveying deck forming the top side of the plenum chamber of the air slide conveyor.
When using an air slide conveyor in a feeding arrangement for feeding material in the form of fine-divided matter into a concentrate burner or a matte burner of a suspension smelting furnace, it important to create an uniform fluidized material bed in the an air slide conveyor, because the fluidized material bed is at a feeding end of the air slide conveyor divided into several sectors of a fine divided matter feeding channel of the concentrate burner or matte burner.
A problem with such porous metal plates to form the top side of the plenum chamber of the air slide conveyor is that the fine-divided matter can block the pores and be extremely wearing on the porous metal plates, which reduces their service life and has a negative effect on bed uniformity.
Another problem with using thin porous metal plates to form the top side of the plenum chamber of the air slide conveyor in feeding arrangements for feeding material in the form of fine-divided matter into a burner of a suspension smelting furnace is that the porous metal plates may be deformed due to the pressure inside the plenum chamber or that the porous metal plates may be deformed at a receiving end of the air slide conveyor at which the fine-divided matter is received in the air slide conveyor. If the porous metal plates are deformed, the fluidized material bed will not be uniform, because the geometry of the plenum chamber is changed.
The function principle of an air slide conveyor is described for example in publication US 3,773,391.
Publication EP 0 319 596 Al presents a fluidizing gravity conveyor for hot particulate material which includes a heat resistant plate having a plurality of holes for receiving bubble caps or nozzles to disperse air flow from a lower plenum chamber to the upper material chamber. The upper material chamber is suitably lines with heat resistant material. Provisions are made for differential thermal expansion.
Objective of the invention
The object of the invention is to provide an air slide conveyor which solves the above identified problems.
Short description of the invention
The air slide conveyor of the invention is characterized by the definitions of independent claim 1.
Preferred embodiments of the air slide conveyor are defined in the dependent claims 2 to
16.
The invention relates also to the use of the air slide conveyor according to any of the claims 1 to 16 in a feeding arrangement configured to feed fine divided material into a burner of a suspension smelting furnace as defined in claim 17.
Due to the higher thickness of porous ceramic bricks leading to higher stiffness and the micro structure of porous ceramic bricks compared to porous metallic plates, porous ceramic bricks provided for a more even gas distribution through the porous ceramic brick. The advantage of this is that the fine-divided material to be conveyed with the air slide conveyor will be evenly fluidized by the gas flowing through the conveying deck. Another advantage of this is that the velocity of the fluidized material bed will be steadier, which is advantageous particularly if the air slide conveyor is used in a feeding arrangement for feeding material in the form of fine- divided matter into several sectors of a fine divided matter feeding channel of a concentrate or of a matte burner of a suspension smelting furnace, because the fine-divided matter will be evenly distributed into the sectors of the fine divided matter feeding channel of the concentrate or matte burner. Even distribution of fine divided matter in the fluidized material bed causes also fewer pulses in the fluidized material bed, which in turn makes the utilization of process gases such as of oxygen in the suspension smelting furnace better.
The porosity in the porous ceramic bricks is uniform and isotropic and pore size is smaller compared to porous metal plates in which the porosity is anisotropic and inhomogeneous because the structure consists of larger alternating areas of pores and solid metal. This ensures on the microscopic scale a more uniform gas distribution leading to a more uniform fluidized bed. In addition, the pore shape is such that they do not contain sharp edges which prevents the sticking of the material into the pores and it will take longer time before the porous ceramic bricks become blocked.
Due to the fact that porous ceramic bricks can be manufactured to be thicker than the porous metal plates the porous ceramic bricks are not similarly prone to wearing.
Due to the stiffness of porous ceramic bricks, the conveying deck forming the top side of the plenum chamber will not be deformed due to pressure in the plenum chamber or due to impact of the material that is fed onto the conveying deck at a receiving end of the air slide conveyor, and geometry of the plenum chamber will remain unchanged.
